AUTOMOBILE GUN-MOUNT.

Application filed. H0176}.

To all whom "it may concern: I

Be it known that I, SAMUEL N. McGn'eAr a citizen of the United States, residin at Cleveland, in a county of Cuyahoga, i.) "e of @hio, have ented certain new and ful improvements in Automobile G Mounts, of which the following is a o scription, reference being bad to the ace panying drawings, forming a part here My inventioi'i relates to improvements gun mounts more particularly to provements in power driven and automo bile mount-s.

The ect of the invention is to construct a gun mount which shall have a large amount of resiliency and adjustment in passing over rough roads and which maybe conveniently locked so as to produce the greatest possible rigidity and steadiness when the gun in firing action.

A further object of the invention is to mount automatic ordnance on a common form of automobile chassis, the gun being mounted on the metallic frame of the chassis and be ng provided with a looking or tension device by win 1 the chassis may be drawn into a firm and rigid locked engagement with the axle of the automobile.

In constructing automobiles, the engine and transmission device and other mechanical parts are carried rigidly attached to the frame of the chassis and the frame is supported from the axles by spring or resilient connection so as to obtain fr edom of movement and adjustment between the axle and the frame, thus to the greatest possible extent avoiding straining and injury to the engine and other parts due to the movement of the wheels in passing over rough roads, the object being to secure the greatest possible adjustment and the least possible jarring or injury to the working parts of the automobile. In the gun mount the principle of construction. is exactly the opposite, guns being usually rigidly mounted on the wheel axle to secure the utmost rigidity and firmness and consequent accuracy of the gun in firing.

A further object of the present invention is to provide means for moving the spring supported frame of the chassis upon which the gun is carried in such a way that the force which thesup orting springs exert upon the frame will e increased to a considerable degree. whereby the sensitivoness $pecifioation of Letters Patent.

' laid springs to vibrations produced by the *ing of the gun is greatly lessened and the eadiness of the frame or platform upon which it is carried greatly increased.

A further object is to provide.- locking mechanism out of eflective operation or die engaged when the supporting springs are in eir normal condition as when the gun is locl'zin mechanism may be brought into operation to rigidly lock the axle and supporting frame together when the gun is to be fired; thus producing a gun mount in which the supporting frame or platform has the greatest possible freedom of movement while the gun is being moved, and at the same time one in which the supporting to the axle to secure a rigid mount witherv the gun is to be fired.

In the drawings,v Figure 1 is a side view partly in section (-2: the rear portion of an automobile gun uount embodying -my invention. Fig. 2 is a similar view on an enlarged scale showing the means for drawing the chassis downward toward the axle, the arrangement of the cord or band being Figs. 3, i, 5 and 6 are detail views showing modified arrangements of the cords or bands. Fig. 7 is a detail view of the elevating and traversing device.

Referring to the drawings, 1 represents an automatic gas operated one poun or cannon having trunnions 2 mounted in a yoke 3 free to turn in a bearing in an ordinary deck stand'mount 4: which is secured to the frame 5 of the chassis of an automobile.

6 indicates the rear axle of the automobile and 7 indicates the wheels carried by the axle. The frame 5 of the chassis is suphere shown as leaf springs of ordinaryconstruction. The forward end of the frame is supported by springs corresponding to springs 8 from the forward axle and is provided with the usual seat and controlling and steering mechanism (not necessary to be here shown) and the automobile isalso provided with the usual engine preferably connected to the ear wheels for driving (not necessary to be here shown).

The gun mount is provided withany c'onvenient elevating and traversing devices. As shown the traversing device comprises a Patented @ct. 3, i911.
